Conch (instrument)

Conch, or conque, also known as a "seashell horn" or "shell trumpet", is a musical instrument, a wind instrument that is made from a seashell, the shell of several different kinds of very large sea snails.

The shells of large marine gastropods are prepared by cutting a hole in the spire of the shell near the apex, and then blowing into the shell as if it were a trumpet, as in blowing horn. Sometimes a mouthpiece is used, but some shell trumpets are blown without one.
